Installing Debian (Jessie) on an Intel NUC D54250WYK

Product - D54250WYK / boxd54250wykh3 – via e.g. Ballicom or eBuyer

It’s an Intel i5 4250U processor (dual core, laptop processor). Supports up to 16gb of RAM and the Intel 5000 graphics thing in it.

The box itself is really small – and silent. A laptop size hard disk can fit into it (2.5″ hdd).

Issues :

  1. BIOS needs updating before it can be installed (apparently); See Intel’s website – currently here - it’s just a case of downloading the .BIO file and sticking it on a USB stick and pressing F7 on boot and following through the prompts.
  2. Most Linux distros do not yet support the network card (Intel 559/I218-V) – I had to netboot a Debian unstable netboot iso image (from here )

Good things -

  1. BTRFS root filesystem + booting etc just worked with Jessie.
  2. X configuration just works – even though it’s quite a new graphics chipset.
  3. Boot time is VERY fast – currently <5 seconds.

ipmi / linux / dell poweredge SC1435

We recently bought two Dell SC1435 servers off eBay. They seemed cheap and quite well specced (dual 4 core CPUs, plenty of RAM for us) – perhaps ideal for redundant mail servers.

Anyway, they’re IPMI 2.0 compliant – meaning they should be controllable remotely (e.g serial console, forceful power cycling etc without the need for some sort of graphical KVM console or DRAC card.).

Here are some notes on setting up/configuring IPMI support and how it can be used – :

spam (policyd-weight + excommunicado)

1. See http://github.com/palepurple/policyd-weight - I’m trying to make some changes to policyd-weight (something I’ve been using for ages) to make it more configurable and add in a GeoIP patch which I’ve seen floating around.

2. See https://twitter.com/excommunicado and http://blog.hinterlands.org/2013/11/an-update-on-communicado/ - for a DNS Blacklist you might want to use –  using excommunicado.co.uk as a RHSBL has stopped about 700 spammy emails for me already :)

3. See https://github.com/palepurple/policyd-dnsbl-spf-geoip - which should improve on policyd-weight which gave me problems with it’s helo checking etc. It’s easier to configure and hopefully far easier to read the sourcecode  (still perl though ! ).
